Research on the impact of spin coating silver nano clusters on the performance of OLED devices

To achieve uniform distribution of silver nano clusters (SNCs) on substrate and reveal its effect on the performance of organic light-emitting diode (OLED), the SNCs incorporated OLED was fabricated and SNCs were coated by multi-step spin coating. Compared with the device without SNCs film, the brightness and current efficiency of the OLED devices with SNCs film were highly raised. The enhancement is attributed to SNCs induced local surface plasmon (LSP) oscillation, which can increase the radiative rate of excitons on Alq₃ molecules.     

Research on flexible silver nanowire electrode for organic light-emitting devices

By spin-coating silver nanowires(AgNWs) and polymethyl methacrylate(PMMA), applying pressure imprint and plasma treatment, we obtained flat Ag NW thin film with a sheet resistance of 20 Ω/sq and a transmittance of 78% at 550 nm with low surface roughness. No significant change in sheet resistance was observed after cyclic bending(bending radius is 5 mm) test and tape test. After 1 000 bending tests, the change rate of sheet resistance was only 8.3%. The organic light-emitting devices(OLEDs) were prepared by using such Ag NW electrodes and a maximum brightness of 5 090 cd/m² was obtained. Compared with the Ag NWs electrode without any treatment, the present Ag NW electrodes have lower sheet resistance and better hole injection. Our results show spin-coated with flat layers, embossed and plasma-treated Ag NW electrodes are suitable for manufacturing flexible organic optoelectronic devices.     

一种新的混合密码系统

根据非线性动力学中的混沌理论设计了一种混沌序列密码，利用该序列密码与RSA公开密钥算法构造了一种新的混合密码体制．该密码体制的安全性等价于RSA的安全性，但是计算量却远远小于RSA的计算量，该算法既适合于字母文字信息的加密，也适合非字母文字信息的加密．文中给出了一个加密字母文字信息的实例．如果加密汉字计算量会更小一些。

基于改进索引散列树的动态大数据审核方法

为了解决公共审核和数据动态性问题,以及降低计算成本,提出一种改进的索引散列树的数据审核方法。该方法在经典Merkle散列树MHT(Merkle Hash Tree)和BLS签名的基础上,提出一种改进的MHT。增加节点字段,修改MHT树的节点信息,使每个节点信息均包含存储数据块的哈希值和相对索引。通过时间戳字段与MHT的根节点相关联,以提供数据新鲜性。数据分析表明,该方法的不当操作检测概率较高,具有较好的安全性。与其他方法相比,该方法的计算成本较低,服务器和审核者的总体时间复杂度为O(n),验证了对MHT的改进行之有效。     

一种用于UHF RFID标签的超低功耗数字处理机设计

A new architecture of digital processors for passive UHF radio-frequency identification tags is proposed. This architecture is based on ISO/IEC 18000-6C and targeted at ultra-low power consumption. By applying methods like system-level power management, global clock gating and low voltage implementation, the total power of the design is reduced to a few microwatts. In addition, an innovative way for the design of a true RNG is presented, which contributes to both low power and secure data transaction. The digital processor is verified by an integrated FPGA platform and implemented by the Synopsys design kit for ASIC flows. The design fits different CMOS technologies and has been taped out using the 2P4M 0.35 μm process of Chartered Semiconductor.
